Title: Nondestructive inspection for wire and cable
Inventor: TAN MASAYUKI
IPC: G01N23/04
Filed: 1987-12-12
Abstract: PURPOSE:To increase the reliability of a product without providing a specific inspection process and to prevent a wasteful production after the occurrence of a fault, by a method wherein an extraneous substance or the like in an insulator is detected simultaneously with manufacture of a wire or a cable by using a CT device. CONSTITUTION:A conductor 2 from a conductor feeder 1 passes along a running loop and is coated with a polyethylene insulator 5 in sections of an inner-layer extruder 3 and an outer-layer extruder 4. Then, it passes through a heating crosslinking tube 6, a cooling tube 7 and a caterpillar 8 and is wound up as a product by a winder 9. In this case, a radiation applying element 22 which rotates while moving in the direction of running of a cable C coated with the insulator 5 and running, and a radiation detecting element 23 detecting a radiation transmitted through the insulator 5, are provided. By this constitution, a radiographic section signal of the insulator 5 can be taken through the full length of the running cable C, and the presence of an extraneous substance in the insulator 5 can be detected directly by processing this signal.

Title: Two-phase brushless motor
Inventor: SAKAMOTO SATOSHI
IPC: H02P6/10
Filed: 1986-12-25
Abstract: PURPOSE:To prevent as much as possible the scattering in the torque of the title motor regardless of the rotating speed of the same, by a method wherein a waveform, generated by amplifying linearly a waveform obtained from a magnetism detector, is employed for a slant waveform in the vicinity of the switching of the phase of the motor. CONSTITUTION:Circuits 1, 2 constitute linear amplifiers, therefore, the output voltage of a Hall element H1, changed comparatively slowly in accordance with the rotation of a rotor, is amplified while maintaining the waveform thereof as it is and is outputted from operational amplifiers A1, A2. These output voltages mitigate the steep slope of the leading edge and trailing edge of the driving currents of coils L1, L2 which are out ON/OFF by transistors TR1, TR2 through resistors R10, R11. According to this method, electromagnetic sounds and the scattering in the torque may be prevented as much as possible and the mechanical vibration of the title motor may be reduced remarkably.

Title: Method and equipment for monitoring secondary air system in cooperation with exhaust gas system of automobile
Inventor: EERITSUHI SHIYUNAIDAA
IPC: F01N7/00
Filed: 1994-12-19
Abstract: PURPOSE: To perform highly reliable monitoring of the introduction of secondary air, by judging the functioning of a secondary-air system by forming a secondary air stream signal from a specified air-fuel ratio. CONSTITUTION: After starting an engine, a circuit of a secondary-air pump 120 is closed and a valve 122 is opened. Thus, a catalyst 116 is quickly heated up to an operating temperature, and harmful substances-components in exhaust gas at the stage of warming up of the engine 100 are reduced. Next, the air mass flow rate in an intake path 102 is determined based on output signals from an air mass measuring device 106. Successively, the fuel mass weighed per unit time is determined based on the injection time and the engine speed, and further the air-fuel ratio of a mixture drawn in the engine 100 is determined. On the other hand, the air-fuel ratio prevailing in an exhaust gas passage 104 on the downstream side of the opening of a secondary- air conduit pipe 118 is determined.  Furthermore, the secondary-air flow rate is obtained based on the air-fuel ratio prevailing in an exhaust gas passage 104 and the air fuel ratio prevailing in an air intake path 102. The functioning is judged with respect to the determined secondary-air flow rate.

CONSTITUTION:A selection signal is transmitted to a multiplexer 4, which is connected to a specified burning in board 6 in a controller 3 in accordance with signals from a host computer 9. In addition, the controller 3 transmits pattern data to a pattern generator 7 in accordance with the signals from the computer 9. The generator 7 transmits a specified pattern signal to the board 6. IC to be inspected is inspected by the pattern signal, whose resulted signal is transmitted to a logic analyzer 5 through the pultiplexer 4. In the analyzer 5 the resulted signal is sampled by the supply of a trigger signal from the generator 7 to transmit to the computer 9 through the controller 3. The computer 9 compares the signal with the previously stored normal resulting signal to discriminate the presence of defects of IC so as to transmit the information of the presence of the defects to a terminal device 10.

At that time, in the case the data terminal is in the state incapable of executing the data communication, it sends a message that it interrupts the communication, and besides, after storing it in the communication control device 200 too as an abnormally finished data communication call, it releases the data communication call. Thus, the excessive charge is never charged.

Title: Suction hole body of vacuum cleaner
Inventor: OMOTO SHUHEI
IPC: A47L9/04
Filed: 1994-12-20
Abstract: PURPOSE: To improve rotating efficiency of a turbine by making the cross-sectional area of the lower part of an air path surrounding the outer periphery of the turbine and making the open air sucked from a suction hole flow from the upper part of the blade to the lower part thereof and making it flow to a communicating hole smaller than the cross-sectional area of the upper part. CONSTITUTION: A dust collecting room becomes negative pressure by action of a vacuum cleaner main body and a suction room 13 becomes negative pressure through a hose. Air flows in the arrow mark B1 direction from a suction hole 16 by this negative pressure and dust, etc., are sucked. At the same time, open air is sucked into an air path 32 of a turbine room 20 from a suction room 13 to generate an air flow flowing along the air path 32 and an air flow in the arrow mark Q direction flowing to a communicating hole 36 and a turbine 21 is rotated thereby. In this case, the flow velocity of the air flow in the arrow mark Q direction flowing from the air path 32 becomes faster in the upstream side of the blade 24 and decreases in the downstream side.  However, as the diameter of a cylindrical part 35 surrounding the periphery of the turbine becomes smaller from the intermediate part to the lower part, the flow velocity of the air flow can be made uniform in the upstream side and the downstream side of the blade 24 and,7 as a result, the turbine can be rotated with good efficiency.
